so if you like drips, well your just in luck. this marker is one of the most durable long lasting best performing markers on the market. made with thick plastic that is very tough. A perfect flow system wich makes perfect drips. the nibs are double sided so when the other waers down. theres just one thing, THE INK SUCKS @#*. watery completly not un buffable. if OTR would just make a good ink this would be the best pen on the market. ( OTHER THAT PILOTS OF COURSE ) just mix up a batch of your own ink and your good to go. pretty easliy refilable, but ur gonna need some gloves. MY FAVORITE :)
